Discussion Overview

The discussion revolves around the performance of a DC booster circuit powered by a 12V battery, specifically addressing the issue of voltage drop in the battery and the booster circuit. Participants explore potential factors affecting battery longevity and voltage stability under load.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant notes that the battery voltage decreases when powering the DC booster circuit and seeks advice on prolonging battery life without voltage loss.
  • Another participant inquires about the energy rating of the battery in Amp-hours, the current drawn from the battery, and the load characteristics of the booster circuit, including output voltage and current.
  • A later reply reiterates the request for the battery's energy rating and current measurements, while also asking for details about the load on the booster circuit.
  • Participants mention that the output voltage of the booster circuit is approximately 40V but express uncertainty about the battery's energy rating and load specifics.

Areas of Agreement / Disagreement

Participants do not reach a consensus, as there are multiple inquiries and requests for information without definitive answers or solutions provided. The discussion remains unresolved regarding the specifics of the battery's performance and the booster circuit's load.

Contextual Notes

Limitations include a lack of information about the battery's energy rating, current measurements, and the load characteristics of the booster circuit, which are necessary for a thorough analysis.

I use a 12V battery to power a DC booster circuit. After just a moment, my battery's voltage decreased, causing the booster circuit to also decrease its voltage. Is there any way to make the battery last longer without losing voltage? Thanks

What is the energy rating of your battery (in Amp-hours)? What current do you measure out of the battery when it is driving the boost circuit? What is the load of the boost circuit (output voltage and current)?

The output voltage of the booster circuit is about 40V, and I don't know what the energy rating of the battery is (I use a GP 23A 12V battery).

Link to the datasheet please. What is the load? What is the output current?

(pulling teeth here...)
